LAMP-BURNER.

Specification of Letters Patent.

Patented March 2'7, 1906.

To all whmn it may concern.-

Be it known that I, EVERETT D. HoLLEY; a citizen of the United States,residing at Forestville, in the county of Hartford and State ofConnecticut, have invented certain new and useful Improvements inLamp-Burners, of which the following is a specification.

My invention relates to improvements in lamp-burners; and the objects ofmy improvement are simplicity and economy in construction and efliciencyin operation.

In the accompanying drawings, Figure 1 is a plan view of my burner withthe dome removed. Fig. 2 is a detached plan View of the dome of myburner. Fig. 3- is an enlarged sectional view of the burner on the line3 y of Fig. 1 with the wick-tube in elevation. Fig. 4 is a sectionalView of the gallery on the line 0c of Fig. 1, together with a sideelevation of a portion of the chimney. Fig. 5 is a detached side View ofthe vent tube. Fig. 6 is an end view of the same. Fig. 7 is a detachedside elevation of the wick-tube on the same scale as Fig. 1. Fig. 8 is adetached .side elevation of one of the chimney-holders.

A designates the body of the burner, having the usual screw-threadedneck 9 at its lower part. At the upper edge is the chimney platform orgallery 10, formed in one and the same piece with the said body. Thechimney holders or arms 11 are formed each of a piece of wire doubledupon itself at the upper end of each holder, the two ends 12 of the wirebeing bent laterally in opposite directions from the said arms andcurved in plan view to correspond with the curve in plan view of therolled-over outer edge 13 of the gallery 10. As shown, there are four ofthese arms, and their ends are inclosed within the said rolled-overouter edge 13, with the ends of each arm abutting or nearly abuttingagainst the ends of the adjacent arms. The curved form of the said ends12 when thus tightly inclosed by the rolled-over edge serves to holdthem rigidly in place. By making these arms each from a separate pieceof wire they are cheaply formed and may be set at a uniform distancefrom each other with great precision and convenience. The wick-raisingshaft 14 and spur wheel or wheels 15 are or may be of any ordinaryconstruction. The dishing or curved airlate 16 has its outer edge seatedon a shou der in the upper part of the body A, where it is held in placeby the wick-tube B, the said tube having-shoulders 17 projecting fromeach edge that rest upon an upper face of the air-plate 16 when the saidwick-tube is passed down through the central hole in the said plate anddown through a hole in the bottom plate of the neck 9. The parts maythen be secured firmly together by expanding the lower end of thewick-tube at each edge, as at 18, Fig. 3. The air-plate 16 isperforated, as usual, and is strengthened and stiffened by radial ribs19 struck up or swaged in the metal of the said plate, the perforationsbeing omitted as to that portion of the plate in which the said ribs areformed. The air-tube or vent-tube 20 is formed of a strip of metalhaving flanged edges 21 and one side of the wick-tube, the said stripforming three sides of the vent-tube and the wick-tube forming thefourth side of the vent-tube. At the lower end of the venttube I formtransverse corrugations 22. The holes in the air-plate 16 and bottom ofthe neck 9 for the wick-tube are enlarged on one side for the usual seam23 of the burner-tube, and I make these enlargements wide enough toadmit the vent-tube 20, which is slipped up through the wick-tube holeswith its flanges facing the wick-tube and astride the seam 23 until oneridge of the corrugations 22 strikes the bottom of the neck. It is thenforced into place to carry one ridge through the bottom of the neck,when the edge of the metal in the said bottom rests in a groove of thecorrugations to hold the vent-tube in place, as shown in Fig. 3. Thevent-tube is long enough to extend a little above the top of theair-plate. Two holes 24 and 25 are formed in the body of the burner toreceive and hold the hinge-lug 26 and catch-lug 27 of the cone D. Thehinge-lug 26 stands normally at nearly a right angle to the skirt orbase of the cone and is transversely ribbed, as shown, to somewhatstifien it. This hingelug is passed through the hole 24 until theadjacent edge of the cone rests on the burnerbody. The cone is thenswung on the hingelug to bring the opposite edge, which bears thecatch-lug, down into place, the outer end of the said catch-lug beingdepressed slightly to enter it into the hole 25, when it sna s down intoplace, as shown in Fig. 8. Tlie outer end of the substantiallyhorizontal hinge-lug now bears firmly upon the under face of the metaloutside of the hole 24, whereby the cone is snugly held in place. Thegallery 10 is provided with short radial beads or ridges 28 at the pointdesigned for the chimney-seat, so that the lower end or base of thechimney C is slightly elevated to furnish an air-space, as shown in Fig.4.

I claim as my invention 1. In a lamp-burner, the air-plate having theusual perforations with radial portions in which the perforations areomitted and having thereon the radial ribs, substantially as described.

2. In a lamp-burner having an air-plate wick-tube, and neck with abottom plate, the air-tube consisting of a plate with flanged edges anda transversely-corrugated lower end, the said plate and flanged edgespassing through holes by the side of the wick-tube and held in place bycrowding the corrugated lower end into engagement with the bottom plateof the neck.
